The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
The electronic device according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, which have wireless communication functions, and various forms of User Equipment (UE), mobile Stations (MS), terminal devices (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as electronic devices.
At present, the SRS switching4 antenna transmission function of a mobile phone is a necessary option of a china mobile communication group CMCC in "white paper terminal for china mobile 5G scale test technology", and is optional in the third generation partnership project 3GPP, and the main purpose of the SRS switching4 antenna transmission function is to determine the quality and parameters of 4 channels of channels by measuring uplink signals of 4 antennas of the mobile phone by a base station, perform beam forming of a downlink optimized multi-input multi-output Massive MIMO antenna array for the 4 channels according to channel reciprocity, and finally obtain the best data transmission performance for downlink 4x4 MIMO.
The electronic device may be a 5G NR Mobile terminal or other 5G NR terminal devices, such as a Customer Premise Equipment (CPE) or a portable broadband wireless device (MIFI).
The reasons for defining the receiving module and the transmitting module presented in the embodiment of the application are as follows, (1): (4 x4 MIMO or 4-path diversity reception is needed for downlink 5G NR); (2) TX SRS switching 4-day wire coiling (optional); (3) the switching function (optional) of the transmitting antenna (4) and the frequency range of sub 6GHz are 3.3-4.2G and 4.4-5G. The frequency band is higher than the frequency band of LTE 600-2700 MHz. Therefore, RF cable (coaxial line) loss is large from one side of the main board to the other side and from the main board to the lower board;
and the system sensitivity formula Ps =10lg (KT) +10lg (BW) + NF + SNR,
k boltzmann constant (1.38 × E-23 unit: J/K)
T is absolute temperature (273.15 unit: K) at 20 ℃ and thus T =293.15
NF: noise figure
BW: bandwidth of
SNR: the minimum demodulation threshold is determined by the platform vendor (high-pass, MTK) baseband algorithm.
In this formula, K, T are fixed constants, BW is determined by the test bandwidth, SNR is determined by the system baseband algorithm,
The formula of NF is as follows,
Figure BDA0002898827080000041
wherein NF 1 ＝IL pre－1st LNA +NF 1st LNA Wherein IL pre－1st LNA For insertion loss before the first stage LNA, NF 1st LNA Is the noise figure of the first stage. These 2 are the main contributors to the overall NF.
And then
Figure BDA0002898827080000042
For noise coefficient contribution of later stageIn general, gn>15，NF2～NFn<5, this fraction contributes less to NF.
In summary, in the rf front end design, the overall NF needs to be reduced to improve the sensitivity. And NF 1 NF being a major contributor 1 In addition to using an external LNA to reduce NF 1st LNA In addition, how to reduce IL pre－1st LNA Becomes a crucial improvement, how to reduce the insertion loss before the first stage LNA.
In the embodiment of the application, a 5G NR receiving module and a transmitting module are defined, and the module can be placed near an antenna, so that the purposes of reducing insertion loss before a first-stage LNA and improving the sensitivity of a system are achieved.
